First ultrasound question

Laurel • 30 years old, married and pregnant with #1.

Hi ladies! I am 6 weeks and 5 days along... our first ultrasound (Doctor said it was the "dating ultrasound") is in a few days. Question though... will the technician be able to tell us if the baby is developing and let us hear the heartbeat? Or do we have to wait for our next doctors appointment to get the results? I really hope that we'll be able find out more when we're in the ultrasound clinic as I am sooo anxious to hear if the baby is growing healthily! Can anyone share their experience?
